what is the difference in regular gas vs higher octaine?

Answer 1

Higher octane gas burns more completely in high performance engines. If your car manual does not recommend high octane gas, you will just be wasting money.

Answer 2

91-94 octane premium gasoline vs ordinary 89 octane gasoline have obvious differences in the octane rating. Premium is generally required for hi-compression engines usually those with compression ratios higher than 9.5 to 1 (approx.) The 89 octane can ignite before its suppose to during the compression stroke (knocking) but in addition to that premium gas will remain 'fresh' in the tank over the season while ordinary gas will sour or degrade if not used by a months time. Burning old sour gas will gum up a carburetor and foul plugs.

Answer 3

"The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine. Knocking can damage an engine, so it is not something you want to have happening. Lower-octane gas (like "regular" 87-octane gasoline) can handle the least amount of compression before igniting.

The compression ratio of your engine determines the octane rating of the gas you must use in the car. One way to increase the horsepower of an engine of a given displacement is to increase its compression ratio. So a "high-performance engine" has a higher compression ratio and requires higher-octane fuel. The advantage of a high compression ratio is that it gives your engine a higher horsepower rating for a given engine weight -- that is what makes the engine "high performance." The disadvantage is that the gasoline for your engine costs more. "

Answer 4

Different cars require different levels of octane, which is the measurement of a gasoline’s ability to resist engine knock – a rattling or pinging sound that results from uncontrolled combustion in the engine. The right level of octane will prevent engine knock and help ensure optimum performance. Hopefully, this answers your question. I don't think that I have ever bought anything other than regular unleaded fuel for my vehicles unless I had to because the regular was out.

Answer 5

A couple people answered correctly that higher octane means that the fuel can be compressed more before exploding. That means that there is LESS energy in the gas, not more. It also does not mean that it will burn cleaner than regular.

Answer 6

Many , regular may have less additive package an usually has less octane index , octane measures the capacity of the gas to stand pressure without detonating before it should .capacity to hold energy if you will. The higher the octane the more energy , so more powerful burn , more Hp . but not in all cars .

Answer 7

A lot of people are right with there answers here, that higher octane means less combustion. But one advantage of buying the regular gas is that you are less likely to be cheated by ( i know at least one ) greedy gas station owners who mix the premium with the cheaper gas.

Anti-knock ratio. Grandma vs. Hot Rod

Answer 9

higher octaine gas gives your vehicle better performance and power but if your vehicle isnt made to use it, it can damage your fuel lines and motor.

Answer 10

With the regular gas you get more but it burns faster. With the high octane you get less but it burns slower. Your choice! =<)
